Wannabe architects are being given the chance to improve on the work of stars such as Rem Koolhaas, Bjarke Ingles and Renzo Piano.

Danish-Icelandic artist Olafur Eliasson has put together his installation “The collectivity project” along New York’s High Line, with the public now able to add to the work on display with white Lego blocks.

A selection of architecture firms with current or ongoing projects in the neighborhood were chosen to kick off the installation. Bjarke Ingles Group, David M. Schwarz Architects, Diller Scofidio + Renfro, James Corner Field Operations, OMA, Renzo Piano Building Workshop, Robert A.M. Stern Architects, Selldorf Architects, SHoP and Steven Holl Architects were all asked to build one “visionary” structure or construction for the opening of the project.

But these can be altered at will by visitors – creating an ongoing construction dialogue between top designers and amateur architects.

“The collectivity project” has previously set up camp in public areas in Tirana, Albania (2005), Oslo, Norway (2006) and Copenhagen, Denmark (2008). At the High Line, an elevated outdoor walkway in Manhattan, it is part of a larger group exhibition called “Panorama,” inspired by the site’s urban views and natural setting.
